Convert Megaroentgens to Nanocoulombs per kilogram
Convert Megaroentgens (MR) to Nanocoulombs per kilogram (nC/kg) instantly and accurately.
Conversion Formula
nC/kg = MR × 258000000000
About Megaroentgens
The megaroentgen (MR) equals 258 C/kg. Used only in extreme radiation environments - nuclear detonation effects calculations, prompt gamma pulse environments, and legacy radiation hardness assurance for military electronics specify total ionising exposure in MR(air); calibrated flash X-ray simulators output pulse exposures in MR. 1 MR = 258 C/kg = 10⁶ R.
About Nanocoulombs per kilogram
The nanocoulomb per kilogram (nC/kg) equals 10⁻⁹ C/kg. Used in modern SI-based environmental radiation monitoring; equivalent to ~3.88 µR. National metrology institutes calibrate secondary standard ionisation chambers with responses expressed in nC/kg. 1 nC/kg = 10⁻⁹ C/kg = 10⁻³ µC/kg.
